Abstract

We propose and experimentally demonstrate a low-cost, compact temperature-insensitive inclinometer, which is constructed by connecting a chemically etched fiber Bragg grating to a hollow-core fiber filled with tin. The optical power reflected from the grating is linearly proportional to the inclination angle of the grating and can provide a real-time measure of the inclination angle. Our experimental sensor can measure the inclination angle from 0° to 20° with an uncertainty of ± 0.35° and negligible temperature interference. © 2014 SPIE.
